Documentation page

The documentation for this useful package seems to be lacking and somewhat misleading, see e.g., #85 #57 #15. I'm interested in contributing to RandomMatrices, and would like to learn its internals by adding a standard Julia documentation page.

Is this package still actively being maintained? If so, are the maintainers open to this? Do they have a preference in the documentation formatting?

首先检查 issues #85、#57 和 #15 中提到的文档缺口和容易误导的部分，然后确认该 package 是否仍在维护，以及 maintainers 更倾向于哪种文档格式。与 maintainers 就范围和格式达成一致后，添加一个标准的 Julia 文档页面，即视为完成。
